[0002] With the improvement of environmental awareness and the advancement of science and technology, new energy vehicles that use electricity are gradually becoming the mainstream of the market. These cars are favored by consumers for their advantages such as zero emissions and low noise. However, the battery pack of new energy vehicles generates a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will not only affect the performance and life of the battery, but also may cause safety problems. The battery pack of new energy vehicles is usually composed of multiple batteries, which are closely arranged to provide power for the car. Under long-term or high-load working conditions, the battery pack will generate significant heat accumulation. If the heat dissipation measures are not appropriate, the temperature of the battery will continue to rise, which may lead to battery performance degradation, capacity decay, and even cause serious safety problems such as thermal runaway.

[0039] Furthermore, a movable plate 52 is provided at each opening, and the movable plate 52 is movably connected to the flue 51 through a spring. A plurality of distance sensors 511 cooperating with the movable plate 52 are provided inside the flue 51. When the movable plate 52 moves upward, the corresponding distance sensor 511 is triggered. A controller 15 is also provided in the installation box 1. After the distance sensor 511 is triggered, a signal is sent to the controller 15, and the controller 15 then performs an alarm operation.

[0040] Furthermore, an exhaust pipe 53 is provided at one end of the top cover 5 , all the flues 51 are connected to the exhaust pipe 53 , and a fan 54 is provided in the exhaust pipe 53 .

[0041] In a specific embodiment, Figures 1 to 9As shown, a new energy vehicle battery heat dissipation device based on an intelligent control component proposed in this application is mainly used to dissipate heat from the battery 4 of the new energy vehicle. Its main body is a square installation box 1, which is used to accommodate other components such as the battery 4. A liquid inlet pipe 11 and a heat exchange box 2 are arranged inside the installation box 1, and the liquid inlet pipe 11 and the heat exchange box 2 are respectively located at both ends of the installation box 1, and a liquid outlet pipe 12 is arranged directly below the liquid inlet pipe 11. The liquid inlet pipe 11 is used to supply refrigerant into the installation box 1, and the liquid outlet pipe 12 is used to discharge refrigerant out of the installation box 1. A liquid cooling plate 13 is arranged on the inner wall of the bottom of the installation box 1, and five heat sinks 3 are vertically arranged on the liquid cooling plate 13. Both ends of the five heat sinks 3 are provided with flow guide pipes 31 connected to the inside of the heat sink 3. One end of the five heat sinks 3 close to the liquid inlet pipe 11 is connected to the liquid inlet pipe 11 through the flow guide pipe 31, and one end of the five heat sinks 3 close to the heat exchange box 2 is connected to the upper end of the heat exchange box 2 through the flow guide pipe 31, and the two ends of the liquid cooling plate 13 are respectively connected to the liquid outlet pipe 12 and the lower end of the heat exchange box 2.

[0042] In addition, there are four gaps between the five heat sinks 3, and three baffles 32 are arranged in the gaps between every two adjacent heat sinks 3, for a total of twelve baffles 32. Figure 2 As shown, the five heat sinks 3 and the twelve baffles 32 together form sixteen storage cells of the same size. Each storage cell stores a battery 4, and all the batteries 4 together form a battery pack. It should be noted that in other embodiments, the number of heat sinks 3 and baffles 32 can be adjusted accordingly according to the specifications of the battery pack. The more batteries 4 that make up the battery pack, the more heat sinks 3 and baffles 32 there are; conversely, the fewer batteries 4 that make up the battery pack, the fewer heat sinks 3 and baffles 32 there are.

[0043] The refrigerant used for heat dissipation starts from the liquid inlet pipe 11, passes through the heat sink 3 through the guide pipe 31, and then reaches the upper end of the heat exchange box 2, and then starts from the lower end of the heat exchange box 2, passes through the liquid cooling plate 13, and then is discharged from the installation box 1 through the liquid outlet pipe 12, thus constructing a circulation route of the refrigerant, thereby dissipating the heat of the battery pack in the installation box 1. Specifically, the heat sink 3 dissipates heat on both sides of the battery 4, and the liquid cooling plate 13 dissipates heat on the bottom of the battery 4.

[0044] Each of the five heat sinks 3 has a guide tube 31, and the five guide tubes 31 are connected to the liquid inlet pipe 11. Each guide tube 31 is provided with a regulating valve 33 at one end close to the liquid inlet pipe 11. There are five regulating valves 33 in total, and each regulating valve 33 corresponds to a heat sink 3. By controlling the regulating valve 33, the flow rate of the refrigerant entering the heat sink 3 corresponding to the regulating valve 33 from the liquid inlet pipe 11 can be controlled, so as to achieve dynamic adjustment of the heat dissipation effect. Specifically, each baffle 32 is provided with a temperature sensor, and these temperature sensors can detect the temperature of each battery 4 in the installation box 1. A controller 15 is also provided in the installation box 1. In actual use, a preset temperature can be set first. When the temperature sensor detects that the temperature of a battery 4 exceeds the preset temperature, the temperature sensor will send a signal to the controller 15, and the controller 15 will then control the regulating valve 33 to increase the refrigerant flow rate of the heat sinks 3 on both sides of the battery 4 exceeding the preset temperature, and reduce the refrigerant flow rate entering other heat sinks 3, thereby enhancing the heat dissipation effect of the battery 4. In this way, the heat sinks 3 on both sides of the battery 4 that exceeds the preset temperature can take away the heat generated by the battery 4 at a faster speed, thereby reducing the temperature of the battery 4. At the same time, in order to maintain the temperature balance of the entire battery pack, the regulating valve 33 will also reduce the flow of refrigerant entering other heat sinks 3 accordingly. This can not only avoid unnecessary energy waste, but also ensure that other batteries 4 operate at a suitable temperature. Through this design, the present application can dynamically adjust the heat dissipation intensity according to the actual temperature changes of the battery 4. When the temperature of the battery 4 rises, the system will automatically enhance the heat dissipation effect; when the temperature of the battery 4 drops, the system will correspondingly weaken the heat dissipation effect. This targeted heat dissipation method not only improves the heat dissipation efficiency, but also extends the service life of the battery 4.

[0045] It should be noted that a plurality of channels 34 for the refrigerant to pass through are arranged inside each heat sink 3, and a spoiler 35 is also arranged inside the heat sink 3 at one end close to the liquid inlet pipe 11. The spoiler 35 enables the refrigerant entering from the liquid inlet pipe 11 to be fully dispersed when entering the heat sink 3. Guided by the spoiler 35, the refrigerant will be evenly guided to the plurality of channels 34, avoiding the situation where the refrigerant is excessively concentrated in a certain channel 34 or missing in some channels 34, and ensuring that the refrigerant can flow evenly through the entire heat sink 3. This design enables the refrigerant to be more evenly diffused into the heat sink 3, which enables both sides of each battery 4 to be fully cooled, thereby avoiding local overheating. In addition, since the flow of the refrigerant is more uniform, the overall heat dissipation efficiency of the heat sink 3 is also improved. This not only helps to extend the service life of the battery 4, but also improves the performance and stability of the entire battery pack.

[0046] In addition, an annular tube 21 is provided in the heat exchange box 2, and a plurality of fins 22 are provided through the annular tube 21 in the heat exchange box 2. These fins 22 are divided into two groups, which are respectively located on the left and right sides of the annular tube 21. These fins 22 not only increase the heat exchange area, but also improve the heat exchange efficiency between the refrigerant and the surrounding environment. The upper end of the annular tube 21 is connected to the guide tube 31 of the heat sink 3, and the lower end of the annular tube 21 is connected to the liquid cooling plate 13. The refrigerant starts from the liquid inlet pipe 11, absorbs the heat from both sides of the battery 4 on the way through the heat sink 3, and then enters the annular tube 21 from the upper end of the annular tube 21, and flows from both sides of the annular tube 21 to the lower end of the annular tube 21 under the action of gravity. In this process, the fins 22 will continuously absorb the heat in the refrigerant, thereby cooling the refrigerant. In order to further enhance the cooling effect of the fins 22, two ventilation pipes 23 are arranged on the top of the heat exchange box 2, and a set of fans 24 are installed under each ventilation pipe 23. The two sets of fans 24 are located inside the heat exchange box 2, and the two sets of fans 24 are respectively located above the fins 22 on both sides of the annular tube 21. The wind directions of the two sets of fans 24 are opposite, so that one ventilation pipe 23 is responsible for air intake and the other is responsible for air outlet. Such a design forms an air flow cycle in the heat exchange box 2, which can continuously introduce fresh air into the heat exchange box 2 and take away the heat of the refrigerant in the annular tube 21 through the fins 22. After being cooled by the fins 22, the refrigerant will flow into the liquid cooling plate 13 from the lower end of the annular tube 21. A cavity for the flow of refrigerant is arranged inside the liquid cooling plate 13, and a plurality of protrusions are arranged on the upper surface of the liquid cooling plate 13, and a battery 4 is placed between every two protrusions. These protrusions not only increase the contact area between the coolant and the bottom of the battery 4, but also enhance the heat dissipation effect by changing the flow rate of the coolant. When the coolant flows through the protrusions, the flow rate slows down, which enables the coolant to more fully take away the heat at the bottom of the battery 4, thereby achieving a better heat dissipation effect.

[0047] It is worth mentioning that a detachable top cover 5 is provided on the top of the installation box 1, and four flues 51 are provided inside the top cover 5. This is because there are four gaps between the five heat sinks 3, and the batteries 4 are also placed in these four gaps, and the four flues 51 correspond to the batteries 4 in each gap. The number of flues 51 is consistent with the number of gaps between the heat sinks 3, and each flue 51 is used to discharge the smoke generated by the battery 4 in the corresponding gap when thermal runaway occurs.

[0048] In addition, each flue 51 is provided with a plurality of openings on one side facing the battery 4, and a movable plate 52 is provided at each opening. The movable plate 52 is movably connected to the flue 51 through a spring, and a plurality of distance sensors 511 cooperating with the movable plate 52 are provided inside the flue 51. Four distance sensors 511 are provided in each flue 51, because three baffles 32 are provided in the gap between each two adjacent heat sinks 3, and a total of twelve baffles 32. These five heat sinks 3 and twelve baffles 32 together form sixteen storage cells of the same size, and there are four batteries 4 in each gap, and each distance sensor 511 is located above one battery 4. The number of distance sensors 511 and flues 51 is determined according to the number of batteries 4 constituting the battery pack.

[0049] Specifically, in actual use, once the battery 4 has a thermal runaway phenomenon, the battery 4 will swell, and the gas generated will quickly lift up the movable plate 52 in the flue 51 directly above the battery 4 that has failed. Since the distance sensor 511 measures distance by emitting laser, when the movable plate 52 rises, the laser emitted by the distance sensor 511 is blocked by the movable plate 52, thereby triggering the distance sensor 511. After the distance sensor 511 is triggered, it immediately sends a signal to the controller 15. After receiving the signal, the controller 15 will immediately start the alarm mechanism to remind the operator to pay attention. In addition, the rise of the movable plate 52 also allows the smoke generated by the battery 4 due to the failure to enter the flue 51 from the opening, which is convenient for subsequent discharge. At the same time, an exhaust pipe 53 is also set at one end of the top cover 5, and all flues 51 are connected to this exhaust pipe 53. A fan 54 is also provided inside the exhaust pipe 53. When the distance sensor 511 triggers an alarm, the controller 15 will simultaneously control the fan 54 to start, and the suction force generated by the fan 54 will quickly discharge the smoke in the flue 51 from the exhaust pipe 53 out of the installation box 1, which can effectively prevent the smoke from accumulating inside the installation box 1 and posing a safety threat to other components and operators in the installation box 1.

[0050] This design not only ensures that the battery 4 can quickly exhaust smoke when thermal runaway occurs, but also because each battery 4 corresponds to a distance sensor 511, it can help the operator to quickly locate the faulty battery 4 afterwards, greatly improving the convenience and efficiency of maintenance.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
